Do you guys run fuel system/injector cleaner through your cars? If so, what brand seems to be the best
at cleaning the carbon and such?

 

One thing I've noticed about my G is it hates cheap gas. I was running Mapco gas for several years and every few months having to run Techron thru in the gas (which is the best imo). Since I have started using Texaco gas which has Techron already in it I haven't had to use an injector cleaner since. On the Mapco gas I would get a hesitation on acceleration which hasn't happened again since switching to Texaco. Figured I'd share... I've had my car for 4 years.

 

Ah okay. I’ve never had good mileage on Mapco or Costco gas on most any vehicle I’ve owned.
I just bought this car and was wondering. I filled up yesterday with Chevron and it said it had Techron so maybe that will have good results.

thanks!

 

Costco gas has the most detergent additives of just about any fuel out there. Just keep using premium as the VQ37VHR was designed for it!

 

Look up What_wires page on instagram. I have a couple of videos of the oem 390cc orange Denso injectors running in my injector cleaner.
I have a total of 6 sets, they all flow a bit different from each other. No cleaner will clean the Pump assembly filter nor the injector filter basket.
Any type of non chemical debris like sand and rubber from will never come out chemically. I also show what running straight carb cleaner + pulsation does as afar as cleaning.
It cleans them for sure but there is never any consistency. These are pulled from running and JY engines. From 70-200k miles.

Most folks try to make sure all switches and sensory as well with other parts of the car are even but injectors seem to be at the last place of many and does contribute in a smoother balance of an engine.

This, increased gap in spark plugs from age and baby exhaust leaks as well as air leaks contribute to many of the VHR misfires.

 

Wow that's great information. I will go check your instagram out for that.

But, as a general rule of thumb, what fuel do you most commonly run in these cars? I have most all the major brands around me.

 

Anything with Techron or Shell will have dependable detergents which have history of being dependable.
Outside of this a newer high traffic gas station would have the freshest of gas along with newer filters.

Again I repeat, most cleaners do ok on the cleaning aspect of it but they cant be too strong or they'll start deteriorating other components in the fuel system which is why you'll never get an instant result.
Those inconsistent results point to an even dirtier system. They might make the car run better but it will never be a resolve just a temporary solution that enventually comes back or requires the individual to now start doing a few bottles to make the changes appear again.
With a manual injector clean you can now rely on data that not only they are clean but that they are even which is the most important part

Many times Drano doesnt work for clogged piping. Many times they have to be manually cleaned.

 

Yes sir I definitely see the point. I’ve had a local guy clean injectors for various cars in the past and always had very consistent results with how the cars run after. Cheap insurance.

what’s your price on cleaning a set of these?

 

My apologies, I don't offer cleaning services anymore. It can become quite the endeavor to find a rebuild kit for injectors you don't have. On top of that the finding of these at an affordable price that the customer wont feel is a problem. Lastly once found, it's mainly a minimum of 100 pieces. Over time it lost my interest.

What I use it now for is for checking if they are even. If they are not I send them to local companies to get cleaned and refurbished.

 

Great information sir, thank you!

 

redline fuel system cleaner or liquimoly jectron

redline is aggressive but works amazing

 

Hi Bread. Could you elaborate on aggressive? More of a certain additive? I use the Seafoam injector cleaner in my cars once a year. I fear using it more in the G as the Cats in these cars seem very particular.

On paper, the more reputable valve and fuel system cleaners should work well on our port injected cars (VR30/Q50/60 is direct injected).

 

hello person that replies to all my posts.

redline has more additives and more chemicals that provide a better overall clean. Seafoam is a moderate/mild cleaner, and I can recommend plenty better cleaners that do a better job. If you are a once a year type guy, stop, and start doing it once an oil change, I recommend you use redline if you don't do it that often, you will feel and see a major difference.

Yes our cats are ridiculous, I had mine swapped to HFCs out of necessity, as I was getting a rattle from the inside. Any fuel cleaner will "eat" your catalytic converters, so at this point just run the redline. Trust me, it will make a difference.

And make sure you go to like exxon,sunoco,bp,shell dont go to wawa,dashin,sheetz, any "trucker" gas station. Go to reputable places.

The 3 highly recommended by me fuel cleaners are:
1. https://www.walmart.com/ip/Red-Line-...ANER/153463031
2. https://www.walmart.com/ip/LIQUI-MOL...5?athbdg=L1600
3. https://www.walmart.com/ip/VP-Racing...2805/190227823

 

The VQ37VHR engine is port injected. Not direct. Just clarifying...

 

You are correct. Not sure how I got this mixed up. I made the correction above.
